my prison, but I was mistaken; for, taking an enormous key, the gaoler
opened a thick door lined with iron, three and a half feet high, with a
round hole in the middle, eight inches in diameter, just as I was looking
intently at an iron machine. This machine was like a horse shoe, an inch

passes through this hole, and the two ends are connected with the axle of
a wheel which is turned by someone until the prisoner gives up the ghost,
for the confessor, God be thanked! never leaves him till he is dead."
